Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
Check wiring connections for corrosion or damage and clean if necessary.
Reconnect any loose wires ensuring a secure connection.

3. Check and Replace ABS Module

If codes indicate a malfunctioning ABS module, remove the module by:
- Disconnecting electrical connectors.
- Removing mounting bolts using a socket set.
Install the new ABS module by reversing the removal process.
Torque the mounting bolts to the manufacturer’s specifications.

4. Brake Fluid Inspection and Replacement

Locate the brake fluid reservoir and check the fluid level.
If low, top up with the recommended brake fluid (DOT 3 or DOT 4, as specified).
If the fluid appears contaminated, perform a complete brake fluid flush:
- Open each brake bleeder valve and allow fluid to drain until fresh fluid flows out.
- Close the bleeder valve and repeat for all four wheels.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove any panel if necessary to access the switch.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is defective, replace it by removing the mounting screws and disconnecting the wiring.
